NOZZLE FOR WATER-WH EELS.

SPECIFICATION forming part oi Letters Patent N 0. 531,897, dated January1, 1895 Application filed February 27, 1894. gerial No. 501.6?8- (Nomodel.)

In all whom it may concern.-

Be it known that we, FRANCIS M. B001;- wAL'rnR and WILLIAM W. TYLER,citizens of the United States, residing at Springfield, in

the county of Clark and State of Ohio, have invented certain new anduseful Improvements in Nozzles for WVater-Wheels, of which the followingis a specification, reference being had therein to the accompanyingdrawro lugs.

This invention relates to certain new and useful improvements in nozzlesfor use in connection with that class of water wheels known as hurdygurdy wheels, and the object of the invention is to control the amountof water which shall pass into the buckets of the wheel from the nozzlewhich directs the water to them by reducing the size of the streamindependently of the size of the nozzle.

In an application for Letters Patent of the United States filed by usFebruary 5, 1894, Serial No. 499,101, for improvements in water wheels,we provide for controlling the amount of water by diverting more or lessof the 2 5 stream issuing from the nozzle aside from, or

outside of, the buckets.

In this present'invention, instead of diverting the stream by adiverter, we reduce the stream by a reducer. This reducer may beoperated by hand and set in fixed positions with respect to the nozzleorifice, or it may be operated automatically, both of which plans areset forth in our said former application.

In the accompanying drawings on which 3 5 like reference lettersindicate corresponding parts, Figure 1, represents a view looking at thereducer, at its rear side, and toward the mouth of the nozzle; Fig. 2, asectional View of the nozzle on the line a: w of Fig. 1; Fig. 3,

40 a sectional view on the line y y of Fig. 2.

The letter A designates a nozzle of suitable contour to adaptit for useespeciallyin connection with that class of water wheels known as hurdygurdy wheels, wherein buckets are pro 5 vided to receive a stream ofwater and be operated upon by the impact and reactionary effects of thestream. This nozzle differs, however, from the ordinary nozzle in theprovis' ion of grooves or beads B, transversely or cir 5o cularly in oron the face of the discharge end,

for a purpose presently to appear; and it furcharge end of the nozzle.

ther diifers in forming the face of its discharge end on a curve, for apurpose also to presently appear. This nozzle is mounted and held in theproper position with respect to the wheel with which it is to be used.

The letter O refers to a beam by which the nozzle is held, such beamforming a part of the structure with which the nozzle may be used.

Our stream reducer consists of a blade, wall or movable body D, adaptedto travel across and against, or substantially against, the dis- In thepresent case this reducer is connected to arms E, which are mounted upona shaft F as their center of movement. The arms with the reducer may beoperated more or less across the stream or the bore of the nozzle byautomatic means or hand devices, or bya combination or arrange- 7o nientinvolving both; an illustration of which is set forth and illustrated inour said application above referred to.

The reducer is provided with beads G, (or grooves) to match the nozzleface, according to whether it has grooves or beads, for the purpose offorming a joint that will substantially prevent the leakage of waterbetween the nozzle face and the reducer. These joints run in straightlines and are made by these matching male and female parts.

As shown the reducer is formed with three. cutting edges or corners or,b, c. The edges (1. and 6 stand at the sides of the stream to cut offportions of it at each side. If the reducer is adjusted far enoughacross the nozzle the cutting edge a will come into opera tion and cutoff a portion of the bottom of the stream. Thus the stream is reduced bytaking it off at two or three sides.

The inner face of the reducer adjacent to the cutting edges forms ashoulder, obstruction, or wall which opposes the stream,while the edgesproper have a knife-like action so as to shear off the stream, as itwere, in a 5 clean-cut and decided manner. For this purpose it will benoticed that the reducer is beveled off, as shown at c, in the severalfigures, so as to make the edges proper sharp. This form also preventsexcessive dripping of wa- 10o tor and a sort of hanging of the waterupon the reducer, which might otherwise occur to a greater or lessextent. Thus it will be understood that our reducer opposes or obstructsthe water, and thereby holds a portion of it back in the nozzle, Whileit forms asharp decisive cutting edge or cutting edges,by which theportion of the stream which is allowed to escape, is decisively cut orsheared off from that which remains or is held back.

We have shown and described our stream reducer as workingin an arcacross the face of a nozzle, but it is to be understood that should itbe arranged so as to operate in the same manner upon the stream otherthan in an are, or other than with the convex and concave surfaces asshown, or without any convexity or concavity of such surfaces it wouldstill be within the scope of our invention.

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is-

The combination with a nozzle, of'a movable stream reducer having a slotor bifurcation whereby three surfaces are presented, each surface beingbeveled, said reducer being adapted to be adjusted across the face ofthe nozzle, and the width of said slot or bifurcation being less thanthe diameter or bore of the nozzle, substantially as shown anddescribed.

In testimony whereof we affix our signatures in presence of twowitnesses.
